Medical device maker Stryker Corp. (SYK) has named Kevin A. Lobo its president and chief executive, effective immediately. He replaces interim CEO Curt R. Hartman--the company's former chief financial officer--who has decided to pursue opportunities outside of Stryker. Mr. Hartman will stay on as an adviser to the CEO to assure a smooth transition as the Stryker conducts a search for a permanent financial head. Mr. Lobo--who will also sit on the board--joined Stryker in April 2011 and was most recently group president of Stryker Orthopaedics. His prior work experience was at companies like KPMG International, Unilever Canada Ltd., Kraft Canada Inc., Rhone-Poulenc, McNeil Consumer Healthcare and Ethicon Endo-Surgery Inc.
